Andrew Lloyd Webber (born 22 March 1948) is an English composer and impresario of musical theatre. Several of his musicals have run for more than a decade both in the West End and on Broadway. He has composed 13 musicals, a song cycle, a set of variations, two film scores, and a Latin Requiem Mass. Several of his songs have been widely recorded and were hits outside of their parent musicals, notably "The Music of the Night" from The Phantom of the Opera, "I Don't Know How to Love Him" from Jesus Christ Superstar, "Don't Cry for Me, Argentina" and "You Must Love Me" from Evita, "Any Dream Will Do" from Joseph and the Amazing Technicolor Dreamcoat, and "Memory" from Cats. In 2001. the New York Times referred to him as "the most commercially successful composer in history". (More from Wikipedia)
From the beginning, Jesus Christ Superstar was conceived for the stage by Andrew Lloyd Webber and Tim Rice – just 21 and 25 years old at the time, respectively – but in order to raise money for the ambitious and undoubtedly controversial theatrical production, they decided to record the album first.
Ian Gillan, the lead singer of Deep Purple sang the part of Jesus on the Jesus Christ Superstar album. In addition to Gillan, the presence of rock session musicians like guitarists Neil Hubbard and Chris Spedding, bassist Alan Spenner and drummer Bruce Rowland gives the album more of a rock flavor than most of Andrew Lloyd Webber's later work.
Joseph and the Amazing Technicolor Dreamcoat is another Biblically themed musical created by Andrew Lloyd Webber and Tim Rice and is the first of their productions to be presented publicly, predating Jesus Christ Superstar by several years.
